Why is it important to verify HVAC and electrical capacities in older buildings?

To choose color schemes
To ensure safety and design feasibility
To finalize furniture layouts
To determine site aesthetics

The correct answer is: To ensure safety and design feasibility

Verifying HVAC and electrical capacities in older buildings is crucial primarily for two reasons: safety and design feasibility. Older buildings may not have been constructed to meet current standards, and their systems might not be equipped to handle modern electrical loads or HVAC requirements. By assessing these capacities, designers can ensure that the building can safely accommodate new systems or modifications without risking failures, overloads, or potential hazards. Additionally, understanding the existing capacities allows for informed design decisions, ensuring that any new installations or upgrades to HVAC and electrical systems are both practical and effective. This verification step is essential for compliance with building codes and standards, which are designed to protect occupants and ensure the longevity of the systems installed. When these capacities are not verified, it can lead to costly changes or safety issues during the renovation or design process.
